For mobile phone charging, we have met a variety of questions: Is the original charger the best? Do you need to unplug the phone after fully charged? Do You need to discharge the phone to 0% before you charge the phone for the first time?

somedays ago, I watched a video on TIKTOK, one man use a 87W macbook charger to charge a iPhone and of course I know the result, but the comments are interesting, one is that "87W, your phone will explode because we just use 5W charger to charge our phones", it is funny but I just want to do this test to show you what will happen.

We use a high-power charger to charge a phone. Usually the output of a iPhone charger is 5V/1A, and you will find if you use a iPad charger(5V/2.1), it costs less time to charge. But if we use higher power charger such as 87W laptop charger, will the phone explode?

Of course not, we can have a test, we use high power charger to charge the phones, and we can use our USB tester to test the charging current and voltage, and we need a iPhone and a Android phone to test, the remaining power of them should not be too much or too little.

OK we have three chargers, one 87W charger for MACBOOK, it has USB-C port; one 45W xiaomi USB-C charger; one 65W charger and it has three ports, the max power of USB-C port is 45W. Will they make the phones explode when charging?

and we choose TC66C to test because the USB port are all USB-C

from let to right: 45W xiaomi charger, 87W macbook charger, 65W Zmi charger(45W on USB-C).

then we test the voltage when we use them to charge a iphoneXR

We will use them to charges phone one by one

of course we test the Android phone

the final result:

the remaining battery of android phone is high so the current value is small

we can see they can just charge the phone and nothing happened

Here is the reason:

We use USB-A port as an example, it has four metal strips, they are VCC/D-/D+/GND, VCC/ GND are used to transport port and D+/D- are used to deliver DATA. When you use quick charge mode to charge a phone, they will deliver voltage signals that changes according to a certain standard, once the signal match the phone, the charger will provide high voltage or high current.

In USB-C charger, signal are transported by CC lines, charger will tell the charging information to the phone, and the phone will choose voltage and current it supports. If the phone doesn’t support every protocol, the charger will provide 5V output.

Just like this:

PD charger: I have 5 charging mode

Phone: Roger that, I want 5V/3A charging mode

PD charger: OK, I will provide 5V/3A output

Phone :Roger that PD charger: 5V/3A charging mode is ready

Phone: OK, I got that, now I want 9V/2A charging mode

PD charger: Roger that, I will provide 9V/2A output

Phone: OK

PD charger: 9V/2A charging mode is ready

Phone: OK, I got that, please keep 9V/2A

So, it has no problem to use a high power charger to charge a phone, the chargers will not output the voltage and current directly, you phone decides the charging mode, and it will not explode.

Thank you for reading

But will it blend?

3

you mean the influence of using other chargers? if you use formal charger, they are high quality, and it has no problem

Sorry, I'm just making a little joke.

There's a Youtube channel where they take different items and put them in a blender and destroy them.

They ask, kinda sarcastically, "will it blend?"

no, the “87 watts” is just the power supply

it is not the charger

the actual charger is inside the phone

it only takes what it needs as long as the input voltage is correct

so the 87 watter will just give 5 or 10 of its watts

I Remember the day i plug my laptop charger into my new phone in front of my friends, my friends ’s faces were priceless :exclamation:

if you know what you are doing, you won’t have to worry about anything

7

got it, thank you for telling me this

8

yes, it is the phone that decides the charging mode, not the charger

9

yes, it reminds us that we need to care about the commen knowledge in our daily life

hello, our UM24 and UM25 use USB2.0 male port , but UM34 use USB3.0 male port, so when testing USB 2.0 female port, if the pins do not contact well, the measurement may not be accurate:

the current is not constant throughout the cycle

if you charge a phone that is already 90% full, it may not draw over .25A for that last 10%

12

I don’t understand what’s your meaning
our meter just to measure real current and voltage
only your charge and phone decide the voltage and current

13

for instance, a phone using a 2A charger, may use 2A at the start of the charge, but as the charge goes in, the current goes down

14

of course , all charger are same … as the charge goes in, the current goes down. at about 90%, it will be less than 1A
it is very very normal

15

So, on a tangent, what do you think will happen if it try to use one of these:

Emulator

To charge one of these:

Panasonic fz m1

The OEM charger puts out 16 volts, the emulator is supposed to trick the usb c into putting out 19 volts. What is 3 volts between friends? Am I going to burn up my tablet or will it be able to deal with the extra voltage?

I can’t find an emulator for 5.5 x 2.5 that puts out 16 v, they all seem to put out 19 v.

I don’t know , friends
so sorry
